ALPHATEC SPINE, INC.

A lateral patient positioning system may include a pelvic bolster assembly and a thoracic bolster assembly. Each of the assemblies may be attached to a conventional surgical table frame by the surgical table frame's longitudinal rails. A plurality of adjustment mechanisms and components are provided to allow for easy and safe manipulation of a patient before and during surgery, including sagittal and/or coronal adjustment of a patient in a lateral position.

This disclosure relates generally to mechanical surgical arms having a connector for attaching a surgical tool to the arm across a sterile drape. In various aspects, a drape connector for securing a tool to a surgical arm across a sterile drape includes a flexible collet for receiving a ball of a connection shank of the surgical arm to selectively secure the flexible collet to the surgical arm. The drape connector may also include a lock associated with an inferior end of the flexible collet. The lock may be for adjusting the flexible collet from an unlocked position to a locked position. Further, the drape connector may include a housing for receiving the flexible collet and the lock. The housing defines a window to provide access to the lock to adjust the flexible collet from the unlocked to the locked position.

In various aspects, an expandable implant for use in a surgical procedure includes a distal cage, a proximal cage mechanically connectable with the distal cage, a top expandable assembly, and a bottom expandable assembly. Each of the top and bottom expandable assemblies have a distal portion in communication with a surface of the distal cage and a proximal portion in communication with a surface of the proximal cage. The expandable implant is expandable firstly in a medial-lateral direction, secondly in a lordotic (e.g., angular) direction, and thirdly a cranial-caudal direction. Additionally, the expandable implant may be diagonally symmetrical about a longitudinal axis of the expandable implant.

This disclosure relates to trackers for use in navigated and/or robotic-assisted surgical procedures. A tracker for use in navigated or robotic-assisted surgery comprises a frame connectable to a surgical instrument, and an arm extending from the frame from a first end to a second end. The arm may have a first tracking marker at the second end, where the first tracking marker is for determining a position of the surgical instrument. The tracker may include a second marker disposed on the frame, the second marker for determining a type of the surgical instrument. The tracker may include multiple arms.

A patient support system may include a pelvic bolster assembly and a thoracic bolster assembly. Each of the assemblies may be attached to a conventional surgical table frame by the surgical table frame's longitudinal rails. A plurality of adjustment mechanisms and components are provided to allow for easy and safe manipulation of a patient before and during surgery.

Disclosed herein are surgical retractors and methods of using such surgical retractors where the surgical retractors include a base portion and two retractor blades. The base portion has (a) two extensions, each extension having a receiving area, and (b) and one or more engagement portions. Each retractor blade includes both a blade portion with proximal and distal ends and an arm portion extending from the proximal end of the blade portion. Each arm portion is received by a respective receiving area.

A retractor may include a proximal portion and a distal portion opposite the proximal portion. The distal portion may include first and second blade retractors each having a blade receptacle defined in a first end of a body. The blade receptacle has an opening that narrows to a seat for receiving a blade head, the seat defining a shape that reduces translation, rotation, and/or angulation of the blade head.

Disclosed herein are occipital plates that include a fixation plate portion and at least two extensions integrally connected to the fixation plate portion and extending away from the fixation plate portion. The fixation plate portion has a plurality of through-holes for receiving bone screws that secure the occipital plate to a patient's skull or, specifically, the occiput. Each extension includes a slot for removably receiving a rod connector or a rod-to-rod connector, the slots having an entry area or portion for receiving a connector and a holding area or portion for maintaining the connector in the slot.

A system and a bone fixation plate for preventing a fastener from rotating so as to prevent the fastener from backing out is provided. The system includes a plate having an opening. A retention member having an arm extending into the opening is configured to engage the head of the fastener so as to prevent the fastener from rotating after the fastener is seated within a vertebral body or implant. In one embodiment, the retention member engages a top surface of the head of the fastener. In another embodiment, the retention member engages a side wall of the head of the fastener.

The present disclosure provides a device to restrict interspinous motion across multiple segments of a spinal column in a patient, comprising at least a first ligamentous line attached to a spinous process, a soft tissue in proximity to posterior aspects of a spinal vertebrae, or a pre-existing spinal fixation device or system.
